It returns "aarch64".

------
    freebsd% cat ./osarch.java
    void main() {
            System.out.println(
                "os.arch = "
                + System.getProperty("os.arch", ""));
    }
    freebsd% java ./osarch.java
    os.arch = aarch64

There are some issues in the bug tracker about Java for FreeBSD on
aarch64, so I would guess it is. I don't have any insights into how
much, or if anybody relies on it in production yet, though.

I don't really have an opinion on that. It seems to be supported for
now, both by OpenJDK and FreeBSD, so if you feel like it. I don't have a
32 bit arm system to test for now, so can't help with the output there.

Take care!
